Han Li looked calm on the surface, but his heart tightened.

Immediately afterward, a glimmer of crystal light shone again from the center of his brow, and a semi-transparent Mind Power Sword shot out once more.

Before the Mind Power Sword could reach him, the moment Zhao Gu Zhenren saw it, the light in his eyes had already dissipated. A look of unwillingness and despair flashed in his eyes as he muttered to himself, "How is this possible? How is this possible..."

In the next instant, the Mind Power Sword easily pierced through the bone shield and shot into Zhao Gu Zhenren's brow.

As the sword flew into his sea of consciousness, Han Li was surprised to discover that Zhao Gu Zhenren's sea of consciousness was almost depleted. The little figure formed by his soul was dim and flickering, looking like a candle in the wind, about to be extinguished.

Obviously, he had suffered some kind of serious injury before, and his soul was extremely unstable.

This made Han Li quite surprised, because the means to injure the soul of a Grand Luo Realm cultivator were by no means simple.

Although his previous attack had injured the opponent, it was also a case of injuring himself a thousand while harming the enemy eight hundred, causing him to be unconscious for quite some time. However, according to his estimation, his attack could not have caused such severe damage to the opponent's soul.

Thoughts flashed through Han Li's mind, but his movements did not hesitate in the slightest.

With a low shout, the Mind Power Sword reappeared in his sea of consciousness and struck down with a single blow. Zhao Gu Zhenren's soul offered almost no resistance and was torn apart, then dissipated.

Zhao Gu Zhenren's body froze and stopped moving.

Shi Chuan Kong had just finished setting up the Yin Xiao Double Mirrors and hadn't figured out what was happening, but seeing an opportunity, he immediately activated the double mirrors to shine on Zhao Gu Zhenren.

He crossed his hands in front of him, and the formation in the void flashed with silver light. The two round mirrors then switched positions, bringing with them a powerful spatial force that distorted the space.

However, Zhao Gu Zhenren's Grand Luo body was incredibly strong, and his bones were as hard as gold and stone. In this distorted spatial force, they only twisted and turned slightly, without suffering any substantial damage.

After several attempts, Shi Chuan Kong was unable to crush him.

Seeing this, Han Li raised his hand and a delicate black bone ring slipped off Zhao Gu Zhenren's hand and flew into his palm. A silver firebird shot out from his shoulder and plunged into Zhao Gu Zhenren's body, instantly engulfing him.

Seeing this, Shi Chuan Kong felt relieved.

He had witnessed the power of the Jing Yan Firebird. However, under normal circumstances, it was impossible to directly pose a threat to a Grand Luo Realm cultivator, and it couldn't even break through the body's protective Qi.

The raging silver flames burned fiercely, emitting bursts of "bī bō" sounds. Han Li stared straight at the flames, lost in thought.

"Brother Li, what's wrong?" Shi Chuan Kong asked, puzzled.

"It's nothing, I was just wondering what Zhao Gu Laoer meant by those words he said earlier," Han Li replied after a moment of silence.

"Why bother with all that? Anyway, that guy can no longer pose a threat to us!" Shi Chuan Kong laughed.

About an incense stick of time later, the silver firebird returned, and Zhao Gu Zhenren had been reduced to ashes.

The firebird shrank rapidly and landed in Han Li's palm. With a gentle puff from its mouth, a section of five-colored finger bone relic fell out.

Han Li's eyebrows twitched slightly, and he discreetly put it away.

"Let's go, hurry to Nightfall City," Han Li said, glancing at Shi Chuan Kong.

"Okay."

Shi Chuan Kong responded and flew up first, heading towards the sky.

Han Li put away the Jing Yan Firebird and followed closely behind, soaring into the sky.

As a result, Shi Chuan Kong came to a stop in front of the irregular object suspended in the sky.

"Why did you stop?" Han Li asked.

"We're here," Shi Chuan Kong said.

"You mean... this is Nightfall City?" Han Li raised an eyebrow and asked.

"That's a long story... In short, this divine object is called the 'Key of Empty Realm', and it's the gateway to Nightfall City and other spaces in the Holy Region," Shi Chuan Kong said mysteriously.

"Other spaces... No wonder I felt this thing was strange before, as if it was close at hand, yet far away at the ends of the earth. So it's located in the overlapping of multiple spaces and maintains many spaces. No wonder you said that even if a Lord of Dao came, they might not be able to shake it even a little," Han Li frowned at first, then said with sudden understanding.

"Let's go, we'll enter the city now."

With that, Shi Chuan Kong revealed a smile on his face, flipped his hand, and took out a specially made black magic-patterned token, pressing it against the black cross-section of the lowest branch.

After the black magic-patterned token was attached to the black crystal-like cross-section, it was immediately adsorbed like a magnet, and then gradually integrated into the cross-section.

Immediately afterward, a piece of black light lit up, and a strong spatial fluctuation came from it.

Shi Chuan Kong looked at Han Li, smiled slightly, and stepped into it first.

After Han Li looked around for a while, he also stepped in.

The black light converged, and the two figures disappeared. The strange polyhedron also returned to its original state.

Han Li only felt a dizzying sensation, and spatial forces came tearing from all around, similar to the feeling when riding a teleportation formation, but much greater.

However, this feeling did not last long. Soon, his body lightened, and he found himself in a bright space.

A blazing sun hung in the sky, casting brilliant light. Below, the ground was a stretch of low hills, with green grass as soft as blankets. The sky was high and the land was vast, making one's spirits rise.

Moreover, the demonic Qi here was unusually dense, almost twice that of the outside world. Clusters of purple-black clouds floated in the air, condensed from demonic Qi.

In comparison, the spiritual Qi of heaven and earth was much thinner.

"Brother Shi, is this the space where Nightfall City is located?" Han Li looked around, seemingly marveling.

"That's right! This place is called Nightfall Realm. It was a realm space created by my father himself. We're finally back," Shi Chuan Kong took a deep breath and then said.

As he spoke, he waved his hand and summoned the Black God Flying Shuttle, carrying the two of them forward.

"A realm space created!" Han Li was shocked to hear this.

If it was said that opening up a small-scale secret realm was not too difficult, his current ability was enough to do it. It only required a long time and a lot of materials, but that was only to create a relatively stable, rigid space.

The space in front of him was different. It was no different from the demonic realm outside, containing the profound artistic conception of the sun, moon, stars, heaven, and earth, which could not be compared at all.

He secretly marveled at the Demon Lord's Heaven-reaching methods, which he could not imagine or compare with his current self.

However, endless fighting spirit and yearning also welled up in his heart. As long as he continued to cultivate diligently, he might be able to reach that realm in the future.

"It's still about half a month's journey from here to Nightfall City. We were delayed on the road for too long, so we need to speed up," Shi Chuan Kong frowned slightly, seemingly feeling that the Black God Flying Shuttle was too slow.

He flicked his sleeve, and with a soft "bang," a purple talisman shot out. After a flash of light, it burst out with countless purple runes, submerging the Black God Flying Shuttle and then quickly attaching to it.

The front end of the Black God Flying Shuttle became curved, turning into a curved bird's head. A purple light flashed in the middle, and with a "puff," two wide purple wings more than ten feet long condensed.

The Black God Flying Shuttle hummed, and its speed suddenly increased by nearly half, turning into a long purple-black rainbow, flying forward at lightning speed.

"Fellow Daoist Shi, since your brothers and sisters know that our destination is Nightfall City, the road ahead may not be safe. We should still be careful," Han Li reminded him at the sight of this.

"Haha, Fellow Daoist Li, don't worry. If we were outside, we would naturally have to be cautious. But this is Nightfall Realm. This area within a million miles is under the surveillance of my father's Boundless Heavenly Eye. Those people would never dare to act recklessly here. We are completely safe here," Shi Chuan Kong said with a laugh.

Hearing this, Han Li was secretly shocked by the Demon Lord's divine powers, but also felt a little awkward.

He was not accustomed to being constantly monitored by others.

"Fellow Daoist Li, don't worry. My father is only monitoring Nightfall Realm to ensure stability and will not investigate everything in detail," Shi Chuan Kong said again, seeming to see Han Li's concerns.

"Fellow Daoist Shi, there are some things I haven't asked you along the way. Now that we are approaching Nightfall City, please enlighten me," Han Li nodded and asked.

"Feel free to speak your mind," Shi Chuan Kong did not show any surprise, as if he had expected Han Li to ask this question.

"Your trip to Nightfall City must be to participate in something important, right? You went through all kinds of hardships to bring the Rota Pi Pa back to Nightfall City, and your brothers and sisters want to seize the Rota Pi Pa, also for this matter, right?" Han Li asked with a flicker in his eyes.

"I originally planned to explain this to Fellow Daoist Li when we arrived in Nightfall City. Since you asked now, I will tell you. You are right, my return to Nightfall City is indeed for an important matter. This matter concerns the hundreds of millions of living beings in the Holy Region. No matter what, the Rota Pi Pa must be safely delivered," Shi Chuan Kong said in a deep voice after a moment of silence.

"Oh, what is it?" Han Li asked with some surprise.

"The election of the next Holy Lord," Shi Chuan Kong said with a slight smile.

"The election of the next Holy Lord? Could it be that your father is going to abdicate?" Han Li was stunned and somewhat surprised.

When one's cultivation reached the True Immortal Realm or above, their lifespan was basically infinite. Unless they encountered an accident or suffered a calamity like the Five Signs of Decay, there would be a change of power. Could something have happened to the Demon Lord?

"My father has been in charge of the Holy Region for many years, and there was no such problem. However, he suddenly announced many years ago that he would elect the next Holy Lord. No one knows the specific reason," Shi Chuan Kong frowned, obviously puzzled by the Holy Lord's decision.

"Fellow Daoist Shi, your return to Nightfall City at this moment, could it be to seize the position of Holy Lord?" Han Li's heart moved, and he immediately asked again.
